Poor service at dstv umhlanga

I went into multichoice umhlanga today 07/08/2021 to cancel my DSTV subscription. I have been a loyal client for over 10 years and never missed a payment. I had already paid my August premium and my billing date is the 1st. I expected a refund for the remaining days of August. The staff member was unable to comply with my request and referred me to the supervisor Andiswa Ntweni. She refused to hear me out and denied my request saying that she can't refund the premium which was already paid for in advance. This is pathetic service. I have already experienced difficulties with DSTV previously and posted complaints as well. DSTV isn't connected at my house anymore and there was no point in paying for the full month when I'm unable to use the service. I can't see myself returning to DSTV or referring anyone to join them. I am in disbelief of this poor service and especially being expected to pay for a service which I don't have.
